Abstract

UNA VALVULA SECCIONADORA DE GAS QUE ES CAPAZ DE MANTENER UNA ESTANQUIDAD FIABLE INCLUSO SI SE EXPONE A UN INCENDIO. EN UNA DISPOSICION, UNA VALVULA ESFERICA SE ESTANQUIZA POR MEDIO DE JUNTAS TORICAS (5, 7), TOMANDO LA VALVULA ESFERICA LA FORMA DE UN CUERPO, UNA BOLA (3) SITUADA DENTRO DEL CUERPO, Y UN VASTAGO (4) QUE SE ACOPLA A LA BOLA A TRAVES DE UNA ABERTURA EN LA PARED DEL CUERPO. EL VASTAGO (4) Y LA BOLA (3) SE ACOPLAN ENTRE SI POR MEDIO DE FORMACIONES DE ACOPLAMIENTO DE COLA DE MILANO. UNA DE LAS JUNTAS TORICAS DE ESTANQUIDAD PUEDEN ASOCIARSE CON UN ELEMENTO ANULAR (12) QUE ES IMPULSADO POR UN RESORTE (14) HACIA LA BOLA (3), DISPONIENDOSE EL ELEMENTO ANULAR (3) DE TAL MODO QUE EN AUSENCIA DE LA JUNTA TORICA SEA IMPULSADO CONTRA LA BOLA (3) Y FORME UNA ESTANQUIDAD ENTRE LA BOLA Y EL CUERPO DE LA VALVULA. LA VALVULA ESFERICA PUEDE UTILIZARSE EN ASOCIACION CON UNA VALVULA SECCIONADORA ACTIVADA POR CALOR, EN LA CUAL SE MONTA EL ELEMENTO VALVULA EN UN MECANISMO CENTRAL IMPULSADO POR RESORTE QUE SE EXTIENDE POR EL INTERIOR DEL CUERPO DE VALVULA. UNA LAMINA BIMETALICA (26, 27) SE EXTIENDE ADYACENTE AL MECANISMO CENTRAL, DISPONIENDOSE LA LAMINA BIMETALICA PARA MOVER EL ELEMENTO VALVULA A UNA POSICION DE VALVULA CERRADA SI LA TEMPERATURA SOBREPASA UN LIMITE PREDETERMINADO.
